I think the text would've looked good, even with the glow, if it was 75% smaller... but those planets are ballin'. Also, there is some smoke around the left of the planet on the bottom is a bit out of place...

I'm going to echo the same theme here. The image itself is pretty spiffy, but the text.... I really don't like the 'motion blur' effect. If you were to do this over (or if you still have the .psd) I would consider working on that text. It could blend with the rest of the image quite a bit better. Also, you might want to try a little less of a pure white color, it just doesn't fit with the overall color scheme you've got going on there.
